Hah! LOVE IT! Memory of tripping at school back in the Daze: I was on windowpane, playing a very difficult, fast, high, flute passage in a college concert band DIRECTLY under our conductor's swinging baton, when the musical notes I was reading just floated off the page and VANISHED. I continued playing and they eventually returned, but I later asked flautists to my left and right if they heard any mistakes from me... Nope... and in hindsight, the director would have said something since his ears were 3 feet from my flute... I had played the piece twice before and the good old subconscious must have kicked in... Whew! I was sweating BULLETS in paranoia... You betcha!
